There's been a host of public and private postmortems following Election Day. Add this one to the can't-be-missed pile: Senior advisers Doug Rubin and Rob Gray, who worked for Deval Patrick and Charlie Baker, respectively, will weigh in next week with their takes on the election. They'll be joined by Frank Phillips, the State House bureau chief of the Boston Globe and Joe Battenfeld of WRKO and the Boston herald. The discussion will be moderated by David Guarino, a former political reporter and vice president of MSL Boston, which is hosting the hour-long talk. It's set for Nov. 9 at 8 a.m. More details are available here.
